.NET for Android error/warning ANDJS0000

Issue

This message indicates that the Java jarsigner command line tool used by .NET for Android reported an error or warning.

Errors reported by jarsigner and other Android command line tooling are outside of .NET for Android's control, so a general error code of ANDJS0000 is used reporting the exact message.

Solution

To learn more about jarsigner and its usage, see the Java documentation here.
